WILLIAM DON, or New YORK, N. Y.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 260,955, dated July 11,1882.

Application filed May 5, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM DON, a citizen of the United States,residing at New York,

in the county and State of New York, have invented new and usefulImprovements in Car- Axle Lubricators, of which the following is aspecification.

This invention consists in the combination of a spring-supported pad, abase-plate supporting the spring, a curved metallic plate on which thepad rests, lugs secured to the pad and forming the bearings for aroller, a wick situated above the base-plate and passing through thepad, asecond wick situated at right angles to the first wick andextending beneath the base-plate and also through the pad, so that thelubricating material from all parts of the box is carried up to thejournal of the axle and distributed by the roller, while the Iubricatorcan be readily compressed for introduction into or removal from theaxlebox. With the parts above named is combined a third wick, the endsof which bear upon the roller, and are supported in lugs depending fromthe supporting-plate of the pad.

In the accompanying drawings, Figure 1 represents a longitudinalsection. Fig. 2 is a transverse section.

Similar letters indicate corresponding parts. In these drawings, theletter A designates the axle-box, and B the axle, the journal of whichis situated in the interior of the box.

My lubricator consists of a base-plate, a, a spiral spring, I),supported by said base'plate, a concave metal plate, o, resting uponsaid spring and fastened on the top of the same, a'pad, cl, fitted intothe concave plate and intended to fit the journal of the axle, andaroller, 6, the axle of which has its bearings in lugs ff, secured to theconcave plate 0, as shown in Fig. 1, so that when the lubricator is inits working position the roller bears against the axle and is caused torevolve by frictional contact therewith.

In order to carry the lubricating material to the journal, I employ twowicks, g h, the ends of which extend through the concave plate 0, andthrough the pad d, and bear against the journal. By referring to thedrawings it will be seen that the wick g is situated above thebase-plate, so that it takes up that portion of the lubricating materialwhich is over said plate, while the wick It is situated in a place atright angles to the wick g and extends beneath the base-plate. By thesemeans all the lubricating material contained in the box A is carried upto the journal, and, as the roller 6 revolves, said lubricating materialis evenly distributed and the surplus is returned to the box.

In order to insure a still more perfect lubrication of the journal, Ihave applied an additional wick, t, the ends of which bear against theroller 6 and extend through lugs j, secured to the concave plate 0, asshown in Fig. 2. By means ofthis additional wick the rollers e aresupplied with some lubricating material, which, if required, istransferred to thejournal of the, axle. At the same time all the partsof my lubricator areconnected in such a manner that the same can becompressed for-the purpose of introducing it into the axle-box or forremoving the same whenever such is desirable. the pad may be supportedby two springs, so as to render the device steady.

What I claim as new, and desire to'sccure by Letters Patent, is-

1. The combination of the base-plate, the spring supported by the same,the concave plate secured to the upper end of the spring and carrying apad for the journal, and a loose roller and two independentwicks,arranged substantially at right angles to each other, and eachconnected with thepad on the concave plate, one of said wicks extendingunder the base-plate and the other extending over the base-plate,substantially as shown and described. j

2. The combination, substantially as hereinbefore described, ot' thebase-plate, the spring supported by said baseplate, the concave platesecured to the top of said spring and supporting the pad, the rollermounted on an axle which has its bearings in lugs secured to the concaveplate, the wicks g h, extending through the pad, and the wick t, theends of which bear against the roller and are supported in lugsdepending from the concave plate.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
